An improved apparatus and process for use in the treatment of organic and inorganic wastes wherein the reactor has a semipermeable membrane positioned between the gas phase and the liquid phase. The semipermeable membrane is selected to control the flow of selected gases and particularly oxygen and nitrogen from the gas phase to the biomass or liquid phase in a ratio greater than 1 part of oxygen to 4 parts of nitrogen. The membrane also controls the flow of carbon dioxide from the liquid phase to the gas phase.
